1. A sorting device that sorts a specific material type matter and another material type matter from sorting objects, the sorting device comprising:
a conveyor that conveys the sorting objects in a placed state in one direction, the sorting objects having the specific material type matter and the other material type matter other than the specific material type matter mixed, and causes the sorting objects to fly at a forefront portion of the conveyor;
an identification part that identifies composition of the specific material type matter placed on the conveyor;
an air blower that generates an airflow in a flying-out direction of the sorting objects;
an upper rectifying plate disposed along a flight path of the sorting objects above the flight path;
a lower rectifying plate disposed along the flight path obliquely below the forefront portion of the conveyor under the flight path; and
a plurality of injectors that are disposed above the flight path so as to be directed to the flight path, and inject pulse air to the specific material type matter flying from the conveyor,
a control device configured to control operations of the conveyor, the air blower, the identification part, and the plurality of injectors,
wherein the control device is configured to generate the airflow having a wind velocity distribution including a plurality of wind velocities,
wherein a maximum value of the plurality of wind velocities is located less than 10 mm downward in a vertical direction from a surface of the upper rectifying plate to a surface of the conveyor at the forefront portion of the conveyor,
wherein a ratio obtained by dividing the maximum value by a wind velocity of the plurality of wind velocities in the vicinity of the surface of the conveyor is 4 or more, and 12 or less,
wherein the airflow has a wind velocity equal to the wind velocity in the vicinity of the surface of the conveyor in a range other than less than 10 mm from the surface of the upper rectifying plate.
